Before the Brooklyn Bridge was built, there was no way to cross the East River from Brooklyn to Manhattan, or Manhattan to Brooklyn, except by boat. Traveling between them was extremely inconvenient. The Brooklyn Bridge changed all that. It made commuting much easier; it was now possible for people to live in Brooklyn, but work in Manhattan. It is not a coincidence that the five boroughs -- which at the time were separate cities -- incorporated into one city in 1898, only 5 years after the bridge opened. The Brooklyn Bridge helped bind the boroughs together into one city.
